One more earthquake strikes Philippine island on yesterday. It has the magnitude of 6.8.  The Philippines Island is located in the Pacific Rim, which has been the receiver of many earthquakes during recent months.  Japan, Hawaii, & Indonesia have all go down victim to earthquakes, even if they didn’t cause immediate damage.

More than the Pacific Rim, Chile, Haiti, Turkey, & the US have recently had quakes.  Chile & Haiti received the brunt of the force, as devastation has occurred in both those countries.  The poor area of Port-au-Prince has been leveled in some areas. The Chile earthquake creates more damage & also moved the axis of the earth.

One more earthquake hits in eastern Maine were from a magnitude 3 earthquake. No wounds or damage was reported from the Tuesday afternoon quake felt mainly in the Bucksport area. The U.S. Geological Survey said the quake was reported at 4:42 p.m. Eastern time & was cored 7 miles east-northeast of Bucksport.

Chile’s President Sebastian Pinera nonstop his tour of earthquake affected areas on Thursday with a little stop in the tsunami-ravaged town of Constitucion.

The recently-inaugurated leader left heads-of-state who had go to his swearing in ceremony only with his wife at a celebratory lunch so he can fit in a lightning-stop to Arancagua, the magnitude of a 6.9 aftershock on Thursday that had rattled the day’s official activities.

That delayed his appearance at Constitucion, where a crowd stayed outside the city’s deeply-damaged main church for him to reach. Earlier in the day, residents had scrambled for the hills in Constitucion after the navy issued a tsunami warning for the mainland, but it was later called off. Pinera agreed that his administration would work about the clock to restore.

Pinera’s election pledges to boost economic growth to 6% a year & create a million jobs have been threatened by the task of the post-quake reconstruction effort.

A powerful 7.2 magnitude aftershock & 4 smaller quakes rocked central Chile on Thursday, on time a tsunami warning minutes previous to Sebastian Pinera was sworn in as the new president.

The quake, which struck 85 miles south of Valparaiso, was the main to hit Chile since a massive 8.8 magnitude quake & tsunami February 27 that killed minimum of 497 people. Chile’s national emergency office gives a tsunami warning for coastal areas after the 5 aftershocks rattled the country on its inauguration day.

2 aftershocks came before the giant one, and 2, measuring 6.9 & the other 6.0, followed, the US Geological Servey said. The major aftershock, measured at 7.2 by the US Geological Survey, set off scenes of panic between dignitaries gathered for Pinera’s opening ceremony, with 7 Latin American heads of state.

Pinera went ahead & took the oath of office at the seat of the Chilean Congress in Valparaiso, and the parliament was evacuated after local officials issued a tsunami alert. The Hawaii-based Pacific Tsunami Warning Center, however, said there was no threat of a “destructive widespread tsunami.”

A moderate earthquake has strike Kosovo, Serbian Radio B92 was quoted as saying on March 10.

The Serbian seismological survey institute has confirmed that a moderate earthquake of a magnitude of 5 on the Richter scale was noticed. The epicenter was close to the town of Zubin Potok, nearly 15km northwest of Kosovska Mitrovica, depending to the report.

Depending to seismological survey director Branko Dragicevic, an earthquake of such magnitude can probably cause damage to weak building structures, B92 was quoted as saying. Presently there were no reports of structural damage or injuries.

The earthquake in Haiti killed nearly 200,000 locals, significantly greater than the Chilean quake. In an earthquake condition, the construction protocol of buildings can play a key part in what the mortality rate is in a quake’s aftermath.  As a result of the earthquakes in Chile & Haiti, with the false tsunami in Hawaii, many national governments are stressing construction protocols that can cope with freak earthquakes & other natural disasters.

The death toll from a 6.0-magnitude earthquake that shook eastern Turkey on Monday around 57, report said. This caused the most deaths in 6 villages around the epicenter in the Karakocan town of the eastern state of Elazig.

The quake struck Basyurt area of Karakocan town at a depth of 5 km at 4:32 a.m. local time (0232 GMT), told the Istanbul-based Kandilli Observatory & Earthquake Research Institute of Turkey’s Bogazici University.

Shakes were also felt in neighboring provinces of Tunceli, Bingol & Diyarbakir. The institute has so far reported 27 aftershocks & more are expected over the next hours & days. Schools are closed for 2 days. The Turkish Red Crescent had offers 500 tents & foodstuff to the quake zone.

It quoted Turkey’s Disaster & Emergency Situation Management Directorate as saying the magnitude of the earthquake was 5.8 on the Richter scale.

A magnitude-6.5 undersea earthquake strike the western shore of Indonesia’s Sumatra Island on Friday, causing horror with no injuries or damages, an official said.

The quake struck late at nighttime 74 miles (119 kilometers) southeast of Pagai Selatan, an island off the western coast of Sumatra, Indonesian Meteorology & Geophysics.

The quake struck 6 miles under the Indian Ocean bed. There was no tsunami possible, he said. When quake strikes people fled their homes & rushed to higher ground. Indonesia rests on a sequence of fault lines that create the extensive archipelago nation one of the most earthquake-prone.

In Taiwan earthquake strike injuring 11 peoples, stopping transport & creates minor damage & fires. The quake also set off 5 fires, with one at a textile factory. Helicopters were used to drop extinguishers to help easiness the blaze.

An earthquake of magnitude 6.4 & depth 23.1km has struck a highly peopled area in the island of Taiwan region having the population as 22.4 million in China. GDACS approximations the likelihood for require of worldwide humanitarian intervention to be average.

The earthquake occurred at morning 8 local time. At the moment a day, more people are at work & therefore more in danger to collapsing office buildings. For the period of traffic hours, people can be affected by collapsing bridges & other road infrastructure.

The earthquake hit 44km from the city of Ping-tung. The nearby more peopled places are Ch’-nu (20km), P’ai-wan-she (19km), T’ao-lin (12km), Tun-na-tsun (12km). It is a rocky region with a maximum altitude of 3702 m.

The earthquake recorded today in Taiwan comes a few days following the shocking earthquake that hit Chile on 27 February this year minimum of 700 dead &  Haiti in January having the toll that go over 300 thousand victims.

A megathrust earthquake is the border between a subducting and an intervening plate. A megathrust earthquake is produced by an unexpected slip along this fault. The world’s largest earthquakes are all refered as megathrust earthquakes.

While megathrust earthquakes have not been experiential in the short (~150 year) written history of the west coast of Canada, there is forceful evidence that they have happened in prehistorical periods. Some of this evidence includes:

• Covered tidal marsh or coastal forest soils point to an abrupt land subsidence of about 1 metre happening at the same time from Vancouver Island to Northern California.

• Alters in tree ring growth from coastal old-growth also suggest a sudden, extensive subsidence and drowning of roots.

• Sand layers on top of the covered coastal marshes, driven in from the offshore bars by the wave of the large tsunami that quick into the subsided coastal region.

• Silt landslide layers on the deep sea floor far off the coast from underwater mudslides, likely caused by strong seismic shaking.

• Tsunami evidence from:
local sources - marine organisms cleaned into and preserved in the bottom muds of coastal lakes that are separated from the ocean by land elevations of some 5 m high level.

distant sources - huge tsunami in Japan with no local Japanese earthquake. Representation this tsunami has exposed that the most recent earthquake for Cascadia was M ~9.0 and happened on January 26, 1700, at around 9 p.m.

JPL research scientist Richard Gross computed how Earth’s rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).

Perhaps more impressive is how much the quake shifted Earth’s axis. Gross calculates the quake should have moved Earth’s figure axis (the axis about which Earth’s mass is balanced) by 2.7 milliarcseconds (about 8 centimeters, or 3 inches). Earth’s figure axis is not the same as its north-south axis; they are offset by about 10 meters (about 33 feet).

By comparison, Gross said the same model estimated the 2004 magnitude 9.1 Sumatran earthquake should have shortened the length of day by 6.8 microseconds and shifted Earth’s axis by 2.32 milliarcseconds (about 7 centimeters, or 2.76 inches).

Gross said that even though the Chilean earthquake is much smaller than the Sumatran quake, it is predicted to have changed the position of the figure axis by a bit more for two reasons. First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake was located in Earth’s mid-latitudes, which makes it more effective in shifting Earth’s figure axis. Second, the fault responsible for the 2010 Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile fault more effective in moving Earth’s mass vertically and hence more effective in shifting Earth’s figure axis. Gross said the Chile predictions will likely change as data on the quake are further refined.

Chile’s President Michelle Bachelet says above 2 million buildings, including 500,000 homes, were spoiled in Saturday’s shocking earthquake. President Bachelet said on Tuesday it is not possible to know at this time which buildings can be remake & which should be pointed.

Ms. Bachelet too said she didn’t have a correct death toll from the earthquake, but is receiving updates each 2 to 3 hours.  The death toll now stands at around 720. Secretary Clinton said the U.S. is ready to help Chile well it can.  She brought with her disaster communications equipment & technical hold up.

Earlier Tuesday, President Bachelet said that raiding & lawlessness will not be tolerated.  She has instructed troops to act with what she called the “severity” necessary to avoid crime. The president has already sent minimum of 10,000 soldiers to cities affected by the earthquake to restore order.
